Macmillan Learning An object of mass 3 M, moving in the +x direction at speed vo, breaks into two pieces of mass M and 2M as shown in the figure. If 0₁ = 69.0 and 02 = 22.0°, determine the final velocities U₁ and 2 of the resulting pieces in terms of vo. VI U2 = 1.155 Incorrect 1.4 VO VO 3M Vo 2M M 1/2₂2 = ? 0. V₁ = ?

A 10.0 kg object moving 20.0m/s South crashes inelastically into a 25.0 kg object at rest. Find the final velocity.

Two football players collide head-on in midair while chasing a pass. The first player has a 100.5 kg mass and an initial velocity of 4.20 m/s, while the second player has a 122 kg mass and initial velocity of -3.9 m/s. What is their velocity (in m/s) just after impact if they cling together? (Indicate the direction with the sign of your answer.) m/s

An Astornaht floating at rest in space has run out of fuel in her jet pack. She realizes that throwing tools from her toolkit in the opppisye direction will help her propel backwards towards her space station. If the astronaut has a mass of 80 kg am she throws a hammer of a mass 4.5 kg at a speed of 4 m/a what will be the appropriate resultant velocity that carries her back to the space station.

A 2.79 kg object initially moving in the positive x-direction with a velocity of +5.35 m/s collides with and sticks to a 2.01 kg object initially moving in the negative y-direction with a velocity of -2.83 m/s. Find the final components of velocity of the composite object. (Indicate the direction with the sign of your answer.)

4. An object, initially travelling at 45 m/s [N], explodes into three pieces. Afterward, the first piece has a mass of 6kg, and travels at 68 m/s [N25E]. The second piece has a mass of 2.5kg, and obtains a new velocity of 26 m/s [N75W]. a) If the third piece has a mass of 4kg, determine its vector velocity after the explosion. b) Determine the change in energy.

A 1 210.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 9 500.0 kg truck moving in the same direction at 20.000 m/s. The velocity of the car right after the collision is 18.000 m/s to the east. (a) What is the velocity of the truck right after the collision? (Give your answer to five significant figures.)  m/s east(b) What is the change in mechanical energy of the car–truck system in the collision? J(c) Account for this change in mechanical energy.

A 4.00 g bullet has a muzzle velocity of 250 m/s when fired by a rifle with a weight of 25.0 N. (a) Determine the recoil speed (in m/s) of the rifle. m/s (b) If a marksman with a weight of 775 N holds the rifle firmly against his shoulder, determine the recoil speed (in m/s) of the shooter and rifle. m/s Additional Materials O Reading
